• Generation Generation -- Burial of source rock to temperature and Burial of source rock to temperature and pressure regime sufficient to convert organic matter into pressure regime sufficient to convert organic matter into hydrocarbonhydrocarbon
• MigrationMigration - Movement of hydrocarbon out of the source - Movement of hydrocarbon out of the source rock toward and into a traprock toward and into a trap
• AccumulationAccumulation - A volume of hydrocarbon migrating into a - A volume of hydrocarbon migrating into a trap faster than the trap leaks resulting in an accumulationtrap faster than the trap leaks resulting in an accumulation
• PreservationPreservation - Hydrocarbon remains in reservoir and is not - Hydrocarbon remains in reservoir and is not altered by biodegradation or “water-washing”altered by biodegradation or “water-washing”
• Timing Timing - Trap forms before and during hydrocarbon migrating- Trap forms before and during hydrocarbon migrating
